Panthers' Charles Johnson: Undergoing back surgery

Johnson (back) is undergoing surgery that will keep him out of action until training camp, Max Henson of the team's official site reports.

Analysis:

The 30-year-old, who recently signed a two-year extension, has been been dealing with back pain and will undergo a minor surgery to address the issue. "Following the surgery, we want Charles as active as possible while still taking the proper precautions," head athletic trainer Ryan Vermillion said. "He will be up and moving around the next day, and we will progressively bring him back." Johnson recorded 26 tackles, four sacks, three forced fumbles and two pass deflections through 13 games last season and shows no signs of slowing down. Look for more updates on his status to come once training camp is underway.
